It has also been found in practice that by reason of the construction and arrangement of the parts indicated the number of elements which must be formed separate from the bowl proper and applied thereto prior to the burning process is minimized as compared with structures for a similar purpose heretofore devised in that said applied parts are limited to the rim, the base,;

the siphon proper, and the cap 24 by which the siphon i-s surmounted and which forms the inlet for communication with the flushing rim.

Special attention is called to the fact that a common and single thickness division or partition wall separates the up and down legs of the siphon, just as a common and single wall separates each leg from the interior of the bowl, so that inspection through either leg will enable the examiner to determine whether flaws, blisters, or other imperfections exist and are of such a character as to detract from the efliciency of the product. 1

Also, it should be noted that when inactive the bowl contains and requires less dead water as a seal than the conventional bowls of the siphonjet types, the reduction in the necessary quantity being approximately one gallon, and consequently, in addition to this economy, the required force and quantity or volume of water to produce or start the siphonic action are minimized, as compared with the ordinary wash-downbowl and particularly as to the siphon-jet type of apparatus.

In connection with the breaks 20, 2i and 22, it is to be further noted that they are so disposed that the passing water is deflected first toward the front of the bowl, then toward the rear thereof and then again toward the front before passing out the outlet 22. This series of deflections occurs in a plane substantially at right angles to the plane of movement of the water when passing from the up-leg into the down-leg of the siphon. In passing from the up-leg to the downleg the water travels crosswise with reference to the bowl and in travelling over the breaks its movement is alternately forwardly and rearwardly in the direction of the length of the bowl. This change of direction given to the flushing water enables it to more effectively dislodge any solid contents which may have been caught in the siphon. Acontinuous flow without any abrupt change of direction such as is herein provided would allow the water to acquire an impetus that would reduce its efiectiveness in dislodging all solid matter.

What is claimed is: a

1. A closet bowl having means for producing a circulatory or gyratory movement of the water in the bowl, and a siphonic outlet having an opening located in the path of said moving water and at substantially right angles thereto.

2'. A closet bowl having means for producing a circulatory or gyratory movement of the water in the bowl, and an outlet having an intake opening located in the path of said moving water and at substantially right angles thereto.

3. A closet bowl having means for producing a circulatory or gyratory movement of water in the bowl, and a siphonic outlet consisting of up and down legs of which both are disposed next to the bowl, the up-leg having an intake opening located inthe path of themoving water and at substantially right angles thereto.
